How to forward WAN via PPPoE to localhost in RouterOS?

Question

Mikrotik

On the local computer, you need to organize a PPPoE connection to an Internet provider that does not use this connection.

What I do:

1)
I create a DHCP client on the ether2 port, into which the provider's cable is plugged. I register a poppy address with the provider. There is a connection.

2)
I go to PPP and create a PPPoE server. As I understand it, it should become a gateway for a computer on the local network. The interface specifies the ether5 port, which looks into the local network.

3)
In the same PPP window, go to the Secrets tab and create a new secret. Apparently, this is an account under which a user from a local computer can log in to the PPPoE server.

How can I configure traffic exchange between PPPoE server and DHCP client?

PS By the way, when I try to connect via PPPoE from a local computer, I get an error 720, although it was expected that the connection would occur, but the network simply would not be available. After all, a PPPoE server on Mikrotik has already been created ...
